Homework: Finalize your experimental design for Lab 3 and email a detailed protocol to your instructor well before the next lab; Generate two figures with legends from your ink concentration experiment: one of one or more photographs of Tetrahymena and the other a graph of the data.

Homework: Plot your A580 data (y-axis) versus time in seconds (x-axis) for the different treatments (you can plot several or all data sets on one graph). Plot all data on the same graph as regression lines for ease of comparison (Appendix E). Include the regression equations. The slopes represent the rates of the Hill reactions. Do not include points that have leveled off. Calculate the rates (change over time of the linear portion of your graphs) and plot those values against your variable (x-axis).

A full paper on your experiment today in the form of a scientific research report is due at beginning of Lab 11. Discuss your results in terms of how the factor that you chose to investigate affects the electron transport rate and the coupling of electron transport with the photophosphorylation of ADP and/or the role of the H+ gradient in these processes. Compare your results to other investigations published in the primary literature. Refer to the "Guidelines for science writing" information found in the Resources section of the wiki.
